Method of implementing an engineering change order in an integrated circuit design by windows
A method of implementing an engineering change order includes steps of: (a) receiving as input an integrated circuit design; (b) receiving as input an engineering change order to the integrated circuit design; (c) creating at least one window in the integrated circuit design that encloses a change to the integrated circuit design introduced by the engineering change order wherein the window is bounded by coordinates that define an area that is less than an entire area of the integrated circuit design; (d) performing a routing of the integrated circuit design that excludes routing of any net that is not enclosed by the window; (e) replacing an area in a copy of the integrated circuit design that is bounded by the coordinates of the window with results of the incremental routing to generate a revised integrated circuit design; and (f) generating as output the revised integrated circuit design.

Method and system for reducing inter-layer capacitance in integrated circuits
The present invention is directed to a method and system of intelligent dummy filling placement to reduce inter-layer capacitance caused by overlaps of dummy filling area on successive layers. The method and system treats each consecutive pair of layers together so as to minimize dummy filling overlaps between each layer. In particular, dummy fill features on each layer may be placed in a checkerboard pattern to avoid overlaps. As such, the present invention may eliminate large overlap area of the dummy patterns on consecutive layers by utilizing intelligent dummy filling placement.
